The term actually originated from a small nut in the south that is very dark and has a hard shell. It is called a niggernut and due to the apes err I mean Africans skin tone resembling this dark nut, the slave traders started to call them niggers.

"When i buy mixed nuts from the grocery store I always separate and throw away the niggernuts."

A word that everyone else is afraid to define except in utter seriousness, for fear of being branded a rascist, in total ignorance of the colloquial usage of the word, its characterization in popular culture, and the populations of people it is used most by.

a term that is racist, as long as the speaker of it is not black. Forbidden on most all of television and other forms of public entertainment, at times referenced to as the "n-word". However, "cracker", a term racist against whites, is a completely acceptable term used in any context of any national broadcast...hmm...

White man: I would like to know why "cracker" and, ahem, "nigger" are not equally forbidden *white man is put on trial for racist slander*
